1.1 Electronic Commerce:

Electronic commerce, commonly known as E-commerce is trading in products or services

using computer networks, such as the Internet.
Electronic commerce draws on technologies such as mobile commerce, electronic funds
transfer, supply chain management, Internet marketing, online transaction processing,
electronic data interchange (EDI), inventory management systems, and automated data
collection systems.
Modern electronic commerce typically uses the World Wide Web for at least one part of the
transaction's life cycle, although it may also use other technologies such as e-mail.

Definition of E-commerce:

Sharing business information, maintaining business relationships and conducting business

transactions using computers connected to telecommunication network is called E-Commerce.

1.2 E-Commerce Categories:

1. Electronic Markets
Present a range of offerings available in a market segment so that the purchaser can
compare the prices of the offerings and make a purchase decision.
Example: Airline Booking System
2. Electronic Data Interchange (EDI)
• It provides a standardized system
• Coding trade transactions
• Communicated from one computer to another without the need for printed orders and
invoices & delays & errors in paper handling
• It is used by organizations that a make a large no. of regular transactions Example:
EDI is used in the large market chains for transactions with their suppliers
3. Internet Commerce
• It is use to advertise & make sales of wide range of goods & services.
• This application is for both business to business & business to consumer transactions.

cooperating supplier who can in-turn schedule their work

1.4 Disadvantages Of E-commerce:

 
 Electronic data interchange using EDI is expensive for small businesses

 is not very good - viruses, hacker attacks can paralise
Security of internet
e-commerce
 
Privacy of e-transactions is not guaranteed
  
 E-commerce de-personalises shopping

1.5 Threats of E-commerce:

Hackers attempting to steal customer information or disrupt the site A server containing customer
information is stolen.
Imposters can mirror your ecommerce site to steal customer money

Authorised administrators/users of an ecommerce website downloading hidden active

content that attacks the ecommerce system.
A disaffected employee disrupting the ecommerce system.

It is also worth considering where potential threats to your ecommerce site might come from,
as identifying potential threats will help you to protect your site. Consider:

Who may want to access your ecommerce site to cause disruption or steal data; for example
competitors, ex-employees, etc.

What level of expertise a potential hacker may possess; if you are a small company that
would not be likely to be considered a target for hackers then expensive, complex security
may not be needed.

1.6 Features of E-Commerce:

 

 based on individual characteristics.
1.7 Business models of e-commerce:
There are mainly 4 types of business models based on transaction party.

Business-to-Consumer (B2C)

In a Business-to-Consumer E-commerce environment, companies sell their online goods to

consumers who are the end users of their products or services. Usually, B2C E-commerce web
shops have an open access for any visitor, meaning that there is no need for a person to login in
order to make any product related inquiry.
Business-to-Business (B2B)

In a Business-to-Business E-commerce environment, companies sell their online goods to other

companies without being engaged in sales to consumers. In most B2B E-commerce environments
entering the web shop will require a log in. B2B web shop usually contains customer-specific
pricing, customer-specific assortments and customer-specific discounts.

Consumer-to-Business (C2B)

In a Consumer-to-Business E-commerce environment, consumers usually post their products or

services online on which companies can post their bids. A consumer reviews the bids and selects
the company that meets his price expectations.
Consumer-to-Consumer (C2C)

In a Consumer-to-Consumer E-commerce environment consumers sell their online goods to

other consumers. A well-known example is eBay.

1.8 E-Governance:

E-governance is the application of information and communication technology (ICT) for

delivering government services, exchange of information communication transactions, integration
of various stand-alone systems and services between government-to-customer (G2C),
government-to-business (G2B), government-to-government (G2G) as well as back office
processes and interactions within the entire government framework.

Through e-governance, government services will be made available to citizens in a convenient,

efficient and transparent manner. The three main target groups that can be distinguished in
governance concepts are government, citizens and businesses/interest groups. In e-governance
there are no distinct boundaries.

Business - to - Government (B2G)

B2G model is a variant of B2B model. Such websites are used by government to trade and exchange
information with various business organizations. Such websites are accredited by the government and
provide a medium to businesses to submit application forms to the government.

Government - to - Business (G2B)

Government uses B2G model website to approach business organizations. Such websites support
auctions, tenders and application submission functionalities.

Government - to - Citizen (G2C)

Government uses G2C model website to approach citizen in general. Such websites support
auctions of vehicles, machinery or any other material. Such website also provides services like
registration for birth, marriage or death certificates. Main objectives of G2C website are to
reduce average time for fulfilling people requests for various government services.
1.9 Different Types of Networking For E-Commerce:
Internet:

The Internet is a global network of computers that allows people to send email, view web sites,
download files such as mp3 and images, chat, post messages on newsgroups and forums and much
more.

The Internet was created by the Advanced Research Projects Agency (ARPA) of the U.S.
government in 1960's and was first known as the ARPANet. At this stage the Internet's first
computers were at academic and government institutions and were mainly used for accessing files
and to send emails. From 1983 onwards the Internet as we know it today started to form with the
introduction of the communication protocol TCP/IP to ARPANet. Since 1983 the Internet has
accommodated a lot of changes and continues to keep developing.

The last two decades has seen the Internet accommodate such things as network LANs and ATM
and frame switched services. The Internet continues to evolve with it becoming available on
mobile phones and pagers and possibly on televisions in the future.

Advantages of internet:
There many advantages to using the internet such as:
E-mail
Email is now an essential communication tool in business. It is also excellent for keeping in touch with
family and friends. The advantage to email is that it is free ( no charge per use) when compared to
telephone, fax and postal services.
Information
There is a huge amount of information available on the internet for just about every subject known
to man, ranging from government law and services, trade fairs and conferences, market
information, new ideas and technical support.
Services
Many services are now provided on the internet such as online banking, job seeking and
applications, and hotel reservations. Often these services are not available off-line or cost more.
Buy or sell products.
The internet is a very effective way to buy and sell products all over the world.
Communities communities of all types have sprung up on the internet. Its a great way to meet up
with people of similar interest and discuss common issues.
A Leading-Edge Image
Presenting your company or organization as leading-edge shows your customers and prospective
customers that you are financially strong, technologically savvy, and ready for the 21st century.
And that you care enough about your customers to take advantage of new technologies for their
benefit. And finally that you have the resources to support your clients in the most beneficial
manner possible.
More and more advertisers on television, radio, magazines, and newspapers are including a Web
address. Now is the time to avoid playing catch-up later.
Improved Customer Service
The companies are available to their customers 24 hours a day, 7 days a week. The Internet never
sleeps. Whenever customer needs information about any company, products or services, they can
access the company‘s Web Page.
Market Expansion
The Internet is a global system. Latest estimates are that there are about 40 million people with
access to the Internet, and this number is growing every day. By simply posting a Web Page you
are also addressing International markets.
Low Cost Marketing
Imagine developing a full color brochure without having to incur the costs of proofs, printers,
wasted paper, long lead times between revisions, and more. Then imagine a full color product or
services brochure that is interactive and which incorporates text, graphics, audio, and/or video.
One that can be immediately updated without incurring the usual costs of product material updates.
Low Cost Selling
Without the cost of direct selling potential customers can get detailed information about your
products or services at any time. And they can easily order your products over the Internet, or
request additional information be sent to them via a request form on your Web page.
Lower Communication Costs
Your time, and your employees time, is valuable. Most businesses and organizations spend time
answering the same questions over and over again. With a Web page you can make the answers
available to everyone immediately. You can also update your Wed page with new information
quickly and easily.
Intranet:

An intranet is a computer network that uses Internet Protocol technology to share

information, operational systems, or computing services within an organization. This term is
used in contrast to extranet, a network between organizations, and instead refers to a network
within an organization.

The objective is to organize each individual's desktop with minimal cost, time and effort to
be more productive, cost efficient, timely, and competitive.

An intranet may host multiple private websites and constitute an important component and
focal point of internal communication and collaboration.

Any of the well known Internet protocols may be found in an intranet, such as HTTP (web
services), SMTP (e-mail), and FTP (file transfer protocol). Internet technologies are often
deployed to provide modern interfaces to legacy information systems hosting corporate data.

Uses of Intranet:

Increasingly, intranets are being used to deliver tools, e.g. collaboration (to facilitate working
in groups and teleconferencing) or sophisticated corporate directories, sales and customer
relationship management tools, project management etc., to advance productivity.

Intranets are also being used as corporate culture-change platforms. For example, large
numbers of employees discussing key issues in an intranet forum application could lead to new
ideas in management, productivity, quality, and other corporate issues.

In large intranets, website traffic is often similar to public website traffic and can be better
understood by using web metrics software to track overall activity. User surveys also improve
intranet website effectiveness. Larger businesses allow users within their intranet to access
public internet through firewall servers. They have the ability to screen messages coming and
going keeping security intact.

When part of an intranet is made accessible to customers and others outside the business, that
part becomes part of an extranet. Businesses can send private messages through the public
 network, using special encryption/decryption and other security safeguards to connect one part
of their intranet to another.

Intranet user-experience, editorial, and technology teams work together to produce in-house
sites. Most commonly, intranets are managed by the communications, HR or CIO departments
of large organizations, or some combination of these.

Because of the scope and variety of content and the number of system interfaces, intranets of
many organizations are much more complex than their respective public websites. Intranets
and their use are growing rapidly.

Advantages:

Workforce productivity: Intranets can help users to locate and view information faster and
use applications relevant to their roles and responsibilities. With the help of a web browser
interface, users can access data held in any database the organization wants to make available,
anytime and — subject to security provisions — from anywhere within the company
workstations, increasing employees' ability to perform their jobs faster, more accurately, and
with confidence that they have the right information.
Time: Intranets allow organizations to distribute information to employees on an as-needed
basis; Employees may link to relevant information at their convenience, rather than being
distracted indiscriminately by email.
Communication: Intranets can serve as powerful tools for communication within an
organization, vertically strategic initiatives that have a global reach throughout the
organization. By providing this information on the intranet, staff have the opportunity to keep
up-to-date with the strategic focus of the organization. Some examples of communication
would be chat, email, and/or blogs. A great real world example of where an intranet helped a
company communicate is when Nestle had a number of food processing plants in Scandinavia.
Their central support system had to deal with a number of queries every day.
Web publishing: allows cumbersome corporate knowledge to be maintained and easily
accessed throughout the company using hypermedia and Web technologies. Examples
include: employee manuals, benefits documents, company policies, business standards, news
feeds, and even training, can be accessed using common Internet standards (Acrobat files,
 Flash files, CGI applications). Because each business unit can update the online copy of a
document, the most recent version is usually available to employees using the intranet.
Business operations and management: Intranets are also being used as a platform for
developing and deploying applications to support business operations and decisions across the
internetworked enterprise.
Cost-effective: Users can view information and data via web-browser rather than maintaining
physical documents such as procedure manuals, internal phone list and requisition forms. This
can potentially save the business money on printing, duplicating documents, and the
environment as well as document maintenance overhead.
Enhance collaboration: Information is easily accessible by all authorised users, which enables
teamwork.
Cross-platform capability: Standards-compliant web browsers are available for Windows,
Mac, and UNIX.
Built for one audience: Many companies dictate computer specifications which, in turn, may
allow Intranet developers to write applications that only have to work on one browser (no
cross-browser compatibility issues).
Promote common corporate culture: Every user has the ability to view the same information
within the Intranet.
Immediate updates: When dealing with the public in any capacity, laws, specifications, and
parameters can change. Intranets make it possible to provide your audience with "live" changes
so they are kept up-to-date, which can limit a company's liability.
Supports a distributed computing architecture: The intranet can also be linked to a
company‘s management information system, for example a time keeping system.

1.10 Wireless Application Protocol:

WAP is a technical standard for accessing information over a mobile wireless network. A
WAP browser is a web browser for mobile devices such as mobile phones that uses the
protocol.
WAP is a specification for a set of communication protocols to standardize the way that
wireless devices, such as cellular telephones and radio transceivers, can be used for Internet
access, including e-mail, the World Wide Web, newsgroups, and instant messaging.
The WAP layers are:

Wireless Application Environment (WAE)

Wireless Session Layer (WSL)
Wireless Transport Layer Security(WTLS)
Wireless Transport Layer (WTP)

Web security:

It is a branch of Information Security that deals specifically with security of websites, web
applications and web services.

At a high level, Web application security draws on the principles of application security but
applies them specifically to Internet and Web systems. Typically web applications are
developed using programming languages such as PHP, Java EE, Java, Python, Ruby,
ASP.NET, C#, VB.NET or Classic ASP.

2.1 Technological convergence:

Technological convergence is the tendency that as technology changes, different

technological systems sometimes evolve toward performing similar tasks.

Digital convergence refers to the convergence of four industries into one conglomerate,
ITTCE (Information Technologies, Telecommunication, Consumer Electronics, and
Entertainment). Previously separate technologies such as voice data and productivity
applications, and video can now share resources and interact with each other synergistically.

Telecommunications convergence, network convergence or simply convergence are broad

terms used to describe emerging telecommunications technologies, and network architecture
used to migrate multiple communications services into a single network.

Convergence in this instance is defined as the interlinking of computing and other

information technologies, media content, and communication networks that has arisen as the
result of the evolution and popularization of the Internet as well as the activities, products
and services that have emerged in the digital media space.

Convergent services, such as VoIP, IPTV, Mobile TV, Smart TV, and others, tend to replace
the older technologies and thus can disrupt markets. IP-based convergence is inevitable and
will result in new service and new demand in the market.

2.2 Technology Implications:

Convergent solutions include both fixed-line and mobile technologies. Recent examples of new,
convergent services include:

Using the Internet for voice telephony

Video on demand
Fixed-mobile convergence
Mobile-to-mobile convergence
 Location-based services
Integrated products and bundles

Convergent technologies can integrate the fixed-line with mobile to deliver convergent solutions.
Convergent technologies include:

IP Multimedia Subsystem
Session Initiation Protocol
IPTV
Voice over IP
Voice call continuity
Digital video broadcasting - handheld

2.3 Collaborative Product Development:

CPD is a business strategy, work process and collection of software applications that
facilitates different organizations to work together on the development of a product. It is also
known as collaborative product definition management (cPDM).

Collaborative Product Development helps individual users and companies manage, share and
view your CAD projects without the cost and complexity of purchasing an entire PDM or
PLM solution. CPD comes in the form of a Software as a service delivery model, which
allows for rapid iterations and little or no downloads and installs.

Exactly what technology comes under this title does vary depending on whom one asks;
however, it usually consists of the Product Lifecycle Management (PLM) areas of: Product
Data Management (PDM); Product visualization; team collaboration and conferencing tools;
and supplier sourcing software. It is generally accepted as not including CAD geometry tools,
but does include data translation technology.

Technologies and methods used:

Clearly general collaborative software such as email and chat (instant messaging) is used within
the CPD process. One important technology is application and desktop sharing, allowing one
person to view what another person is doing on a remote machine. For CAD and product
visualization applications an ‗appshare‘ product that supports OpenGL graphics is required.
Another common application is Data sharing via Web based portals.

Specific to product data

With product data an important addition is the handling of high volumes of geometry and
metadata. Exactly what techniques and technology is required depends on the level of
collaboration being carried out and the commonality (or lack thereof) of the partner sites‘ systems.

Specific to PLM and CAx collaboration

Collaboration using PLM and CAx tools requires technology to support the needs of:

1. People: Personnel of different disciplines and skill levels;

2. Organizations: Organizations throughout an enterprise or extended enterprise with
different rules, processes and objectives;
3. Data: Data from different sources in different formats.

Appropriate technologies are required to support collaboration across these boundaries.

 
 People
Effective PLM collaboration will typically require the participation of people who do not
have high level CAD skills. This requires improved user interfaces including tailorable user

 interfaces that can be tailored to the skill level and specialty of the user.
Improved visualization capabilities, especially those that provide a meaningful view of
complex information such as the results of a fluid flow analysis will leverage the value of all
participants in the collaboration process. Effective collaboration requires that a participant
be freed from the burden of knowing the intent history typically imbedded within and

constricting the use of parametric models.
 
 Organizations
Community collaboration requires that companies, suppliers, and customers share
information in a secure environment, ensure compliance with enterprise and regulatory rules
and enforce the process management rules of the community as well as the individual

organizations.
  
 Data
The most basic collaboration data need is the ability to operate in a MultiCAD environment.
That is, however, only the beginning. Models from multiple CAD sources must be assembled

into an active digital mockup allowing change and/or design in context.

2.4 Content Management System:

A content management system (CMS) is a computer application that allows publishing,

editing and modifying content, organizing, deleting as well as maintenance from a central
interface. Such systems of content management provide procedures to manage workflow
in a collaborative environment.

CMSs are often used to run websites containing blogs, news, and shopping. Many
corporate and marketing websites use CMSs. CMSs typically aim to avoid the need for
hand coding, but may support it for specific elements or entire pages.

Main features of CMS:

The function and use of content management systems is to store and organize files, and
provide version-controlled access to their data. CMS features vary widely. Simple systems
showcase a handful of features, while other releases, notably enterprise systems, offer more
complex and powerful functions. Most CMS include Web-based publishing, format
management, revision control (version control), indexing, search, and retrieval. The CMS
increments the version number when new updates are added to an already-existing file.
Some content management systems also support the separation of content and presentation.

A CMS may serve as a central repository containing documents, movies, pictures, phone
numbers, scientific data. CMSs can be used for storing, controlling, revising, semantically
enriching and publishing documentation.

The content management system (CMS) has two elements:


Content management application (CMA) is the front-end user interface that allows a user,

even with limited expertise, to add, modify and remove content from a Web site without

 
the intervention of a Webmaster.
 
 Content delivery application (CDA) compiles that information and updates the Web site.

2.5 Web Traffic:
Web traffic is the amount of data sent and received by visitors to a web site.
Web traffic is measured to see the popularity of web sites and individual pages or sections within
a site. This can be done by viewing the traffic statistics found in the web server log file, an
automatically generated list of all the pages served. A hit is generated when any file is served.

The following types of information are often collated when monitoring web traffic:

The number of visitors.

The average number of page views per visitor – a high number would indicate that the
average visitors go deep inside the site, possibly because they like it or find it useful.
Average visit duration – the total length of a user's visit. As a rule the more time they spend
the more they're interested in your company and are more prone to contact. Average page
duration – how long a page is viewed for. The more pages viewed, the better it is for your
company.
Domain classes – all levels of the IP Addressing information required to deliver Webpages
and content.
Busy times – the most popular viewing time of the site would show when would be the
best time to do promotional campaigns and when would be the most ideal to perform
maintenance
Most requested pages – the most popular pages
Most requested entry pages – the entry page is the first page viewed by a visitor and shows
which are the pages most attracting visitors
Most requested exit pages – the most requested exit pages could help find bad pages,
broken links or the exit pages may have a popular external link
 Top paths – a path is the sequence of pages viewed by visitors from entry to exit, with the
top paths identifying the way most customers go through the site
Referrers; The host can track the (apparent) source of the links and determine which sites
are generating the most traffic for a particular page.

2.6 Content marketing:

Content marketing is any marketing that involves the creation and sharing of media and
publishing content in order to acquire and retain customers.

It is a strategic marketing approach focused on creating and distributing valuable, relevant,

and consistent content to attract and retain a clearly-defined audience — and, ultimately,
to drive profitable customer action.

Basically, content marketing is the art of communicating with your customers and
prospects without selling.

It is non-interruption marketing. Instead of pitching your products or services, you are

delivering information that makes your buyer more intelligent.
2.7 Call centre:
A call centre is a centralised office used for receiving or transmitting a large volume of
requests by telephone.

An inbound call centre is operated by a company to administer incoming product support

or information inquiries from consumers.

Outbound call centers are operated for telemarketing, solicitation of charitable or political
donations, debt collection and market research.

A contact centre is a location for centralised handling of individual communications,

including letters, faxes, live support software, social media, instant message, and e-mail. A
call centre has an open workspace for call centre agents, with work stations that include a
computer for each agent, a telephone set/headset connected to a telecom switch, and one
or more supervisor stations. It can be independently operated or networked with additional
centres, often linked to a corporate computer network, including mainframes,
microcomputers and LANs.

The contact centre is a central point from which all customer contacts are managed.
Through contact centres, valuable information about company are routed to appropriate
 people, contacts to be tracked and data to be gathered. It is generally a part of company‘s
customer relationship management.

2.8 Components of call centre:

There are 6 key components which should be integrated into the call centre operation:

Location, building and facilities

Customer
Technology
Process
People
Finance and business management

 
 Location, building and facilities

Where a centre is located is critical in terms of the cost of the building but more importantly
the ability to recruit and retain employees to work in the centre. The ease and cost to get to a
centre is important for those employed in the centre but also in the integration with the Head
Office functions that the centre needs to work with. The facilities and working environment is
more critical than for functional line departments because of the intensity with which the
Agents have to sit at their desks and the need to manage resource patterns. Visiting a call centre
and looking at how it might feel to work in it will be extremely telling as to how good the

 centres performance is, but also how the organisation view and treat their employees.
 
 Customer

Customers can be anyone, and the Agent needs to have the skills to be able to adapt their style
and vocabulary to suit different customer types. The Agent talks to more customers in any one
day that any other person in the organisation. If you want to know what is going on with
customers, ask the Agents! With average call durations of less than 3 minutes, how do you
form a relationship and build loyalty from a customer in that time. That is one of the biggest
challenges that the Agents face, especially given many customers do not like the impersonal

 touch that call centres often provide.
 
 Technology

 There are significant amounts of technology available and it is very easy to be bamboozled by
it all! It very much depends on the size and nature of your business as to what you require. The
basic equipment to handle calls is the Automated Call Distributor but these can range from

basic to a Rolls Royce! Many centres do not fully utilise the technology that they have.

In addition there is usually a disjoint between what the technology can do and what it is actually
used for.
 
 Process

Every centre has a multitude of processes, but the biggest challenge that it faces is to
understand the end to end process from the customer perspective. The customer journey is
what happens from the point in time when a customer decides to contact you through to the
completion of that request or transaction. How long does this journey take and what does it
feel like taking the steps along the way. How long is spent waiting? Does the agent have the
customer details to hand? Can the agent answer the query first time? Does the fulfilment when
expected? One very easy but critical way of looking at the customer journey is to mystery shop
the centre and to see what it really feels like to be the customer. Put yourselves in the shoes of

 your key customer demographic type and call your own centre today.
 
 People

People are the most critical asset in a call centre as it is they who really deliver the business
performance. Unfortunately the investment and perception of your staff may be rather poor.
The people (Agents) often have to deal with difficult situations when things have gone wrong
in your organisation and deal with a large volumes of calls that result, whilst not always having
the necessary training or skills. However, the teams in Centres can be very resilient and are
often very social, making the centre a great place to work. There are many different roles on

 offer and so they can a good environment to start and develop a career.
 
 Finance and business management

There will be more management information statistics in a call centre than in any other part of
the organisation. The centre is measured from every different angle but unfortunately, this does

not always give a complete picture!

 One of the most challenging roles is the planning, measuring and reviewing of performance
because so many centres are under pressure from calls and other expectations, that being able
to step back and take an objective view maybe difficult. Most centres are run to very tight

budgets so factors such as turnover of staff will have a huge impact.

2.9 Customer-Premises Equipment:

Customer-premises equipment or customer-provided equipment (CPE) is any terminal and

associated equipment located at a subscriber's premises and connected with a carrier's
telecommunication channel at the demarcation point . The demarc is a point established in a
building or complex to separate customer equipment from the equipment located in either the
distribution infrastructure or central office of the communications service provider.

CPE generally refers to devices such as telephones, routers, switches, residential gateways (RG),
set-top boxes, fixed mobile convergence products, home networking adapters and Internet access
gateways that enable consumers to access communications service providers' services and
distribute them around their house via a local area network (LAN).

2.10 Supply Chain Management:

It is the process of planning, implementing, and controlling the operations of the supply chain with
the purpose to satisfy customer requirements as efficiently as possible. Supply chain management
spans all movement and storage of raw materials, work-in-process inventory, and finished goods
from point-of-origin to point-of-consumption.

Supply chain management must address the following problems:

Distribution Network Configuration: Number and location of suppliers, production facilities,

distribution centers, warehouses and customers.

Distribution Strategy: Centralized versus decentralized, direct shipment, cross docking, pull
or push strategies, third party logistics.

Information: Integrate systems and processes through the supply chain to share valuable
information, including demand signals, forecasts, inventory and transportation.

Inventory Management: Quantity and location of inventory including raw materials, work-
in-process and finished goods.
2.11 Features Of Supply Chain Management:
In electronic commerce, supply chain management has the following features.

o An ability to source raw material or finished goods from anywhere in the world
o A centralized, global business and management strategy with flawless local execution

o On-line, real-time distributed information processing to the desktop, providing total

supply chain information visibility

o The ability to manage information not only within a company but across industries and
enterprises

o The seamless integration of all supply chain processes and measurements, including
third-party suppliers, information systems, cost accounting standards, and
measurement systems The development and implementation of accounting models
such as activity based costing that link cost to performance are used as tools for cost
reduction

o A reconfiguration of the supply chain organization into high-performance teams going

from the shop floor to senior management.

2.12 Components Of Supply Chain Management:

The following are five basic components of SCM.


Plan:
This is the strategic portion of SCM. You need a strategy for managing all the resources that
go toward meeting customer demand for your product or service. A big piece of planning is
developing a set of metrics to monitor the supply chain so that it is efficient, costs less and
delivers high quality and value to customers.

 
 Source:
Choose the suppliers that will deliver the goods and services you need to create your product.
Develop a set of pricing, delivery and payment processes with suppliers and create metrics for
monitoring and improving the relationships. And put together processes for managing the
inventory of goods and services you receive from suppliers, including receiving shipments,
verifying them, transferring them to your manufacturing facilities and authorizing supplier

payments.

 
Make:
This is the manufacturing step. Schedule the activities necessary for production, testing,
packaging and preparation for delivery. As the most metric-intensive portion of the supply
chain, measure quality levels, production output and worker productivity.

 
 Deliver:
This is the part that many insiders refer to as logistics. Coordinate the receipt of orders from
customers, develop a network of warehouses, pick carriers to get products to customers and set

up an invoicing system to receive payments.

 
Return:
The problem part of the supply chain. Create a network for receiving defective and excess
products back from customers and supporting customers who have problems with delivered
products.

2.13 Measuring A Supply Chain’s Performance:

The performance of a supply chain is evaluated by how it reduces cost or increases value. SCM
performance monitoring is important; in many industries, the supply chain represents roughly 75
percent of the operating budget expense. Three common measures of performance are used when
evaluating SCM performance:

Efficiency focuses on minimizing cost by decreasing the inventory investment or value
 relative to the cost of goods sold. An efficient firm is therefore one with a higher inventory

 turnover or fewer weeks‘ worth of inventory on hand.

Responsiveness focuses on reduction in both inventory costs and missed sales that comes 
 with a faster, more flexible supply chain. A responsive firm is proficient in an uncertain

 market environment, because it can quickly adjust production to meet demand.

 value
Effectiveness of the supply chain relates to the degree to which the supply chain creates
 for the customer. Effectiveness-focused supply chains are called ―value chains‖
because they focus more on creating customer value than reducing costs and improving

productivity.

To examine the effect of the Internet and electronic commerce on the supply chain is to examine
the impact the Internet has on the efficiency, responsiveness, effectiveness, and overall
performance of the supply chain.

2.14 Advantages of Internet/E-Commerce Integrated Supply Chain:

The primary advantages of Internet utilization in supply chain management are speed, decreased
cost, flexibility, and the potential to shorten the supply chain.
 
 Speed:
A competitive advantage accrues to those firms that can quickly respond to changing market
conditions. Because the Internet allows near instantaneous transfer of information between
various links in the supply chain, it is ideally suited to help firms keep pace with their
environments. Many businesses have placed a priority upon real-time information regarding

the status of orders and production from other members of the supply chain.

 
 Cost decrease:

Internet-based electronic procurement helps reduce costs by decreasing the use of paper
and labor, reducing errors, providing better tracking of purchase orders and goods delivery,
streamlining ordering processes, and cutting acquisition cycle times.

Flexibility:
The Internet allows for custom interfaces between a company and its different clients,
helping to cost-effectively establish mass customization. A manufacturer can easily create a
custom template or Web site for a fellow supply chain member with pre-negotiated prices
for various products listed on the site, making re-ordering only a mouse click away. The
information regarding this transaction can be sent via the Internet to the selling firm‘s
production floor and the purchasing firm‘s purchasing and accounting departments. The
accuracy and reliability of the information is greater than the traditional paper and pencil
transaction, personnel time and expense is reduced, and the real-time dissemination of the
relevant information to interested parties improves responsiveness. These advantages can
benefit both firms involved in the transaction.
 
 Shortening the supply chain:
Dell computers has become a classic example of the power the Internet can have on a supply
chain. Dell helped create one of the first fully Internet-enabled supply chains and
revolutionized the personal-computer industry by selling directly to businesses and
consumers, rather than through retailers and middlemen. In mid-1996, Dell began allowing
 consumers to configure and order computers online. By 1998, the company recorded 

roughly $1 billion in ―pure‖ Internet orders. By reducing sales costs and attracting customers
who spend more per transaction, Dell estimates that it yields 30 percent greater profit margins
on Internet sales compared to telephone sales.

2.15 Disadvantages of Internet/E-Commerce Integrated Supply Chain:

 
 Increased interdependence:
Increased commoditization, increased competition, and shrinking profit margins are forcing
companies to increase outsourcing and subcontracting to minimize cost. By focusing on its
core competencies, a firm should be able to maximize its economies of scale and its
competitiveness. However, such a strategy requires increased reliance and information
sharing between members of the supply chain. Increased dependency on various members of
the supply chain can have disastrous consequences if these supply chain members are unable

 to handle the functions assigned to them.
 
 The costs of implementation:
Implementation of a fully-integrated Internet-based supply chain is expensive. This expense
includes hardware cost, software cost, reorganization cost, and training costs. While the
Internet promises many advantages once it is fully integrated into a supply chain, a

 significant up front investment is needed for full deployment.
 
 Keeping up with the change in expectations:

Expectations have increased as Internet use has become part of daily life. When customers
send orders electronically, they expect to get a quick confirmation and delivery or denial if
the order can not be met. Increasingly, in this and other ways, customers are dictating terms
and conditions to suppliers. The introduction of Internet-based supply chains make possible
the change to a ―pull‖ manufacturing strategy replacing the traditional ―push‖ strategy that
has been the standard in most industries.

3.1 E-Payment System:

Electronic payment systems are central to on-line business process as companies look for ways to
serve customers faster and at lower cost. Emerging innovations in the payment for goods and
services in electronic commerce promise to offer a wide range of new business opportunities.

Electronic payment systems and e-commerce are highly linked given that on-line consumers must
pay for products and services. Clearly, payment is an integral part of the mercantile process and
prompt payment is crucial. If the claims and debits of the various participants (consumers,
companies and banks) are not balanced because of payment delay, then the entire business chain
is disrupted. Hence an important aspect of e-commerce is prompt and secure payment, clearing,
and settlement of credit or debit claims.

Electronic payment systems are becoming central to on-line business transactions nowadays as
companies look for various methods to serve customers faster and more cost effectively. Electronic
commerce brings a wide range of new worldwide business opportunities. There is no doubt that
electronic payment systems are becoming more and more common and will play an important role
in the business world. Electronic payment always involves a payer and a payee who exchange
money for goods or services. At least one financial institution like a bank will act as the issuer
(used by the payer) and the acquirer (used by the payee).

3.2 Types of Electronic Payment Systems:

Electronic payment systems are proliferating in banking, retail, health care, on-line markets, and
even government—in fact, anywhere money needs to change hands.

Organizations are motivated by the need to deliver products and services more cost
effectively and to provide a higher quality of service to customers.
The emerging electronic payment technology labeled electronic funds transfer (EFT).
 EFT is defined as ―any transfer of funds initiated through an electronic terminal
telephonic instrument, or computer or magnetic tape so as to order, instruct, or authorize a
financial institution.
EFT can be segmented into three broad categories:

Banking and financial payments
Large-scale or wholesale payments (e.g., bank-to-bank transfer)
Small-scale or retail payments (e.g., automated teller machines
Home banking (e.g., bill payment)

Retailing payments
Credit Cards (e.g., VISA or MasterCard)
Private label credit/debit cards (e.g., J.C. Penney Card)
Charge Cards (e.g., American Express)
 
 On-line electronic commerce payments
 
Token-based payment systems

Electronic cash (e.g., DigiCash)

Electronic checks (e.g., NetCheque)
Smart cards or debit cards (e.g., Mondex Electronic Currency Card)

Credit card-based payments systems
Encrypted Credit Cards (e.g., World Wide Web form-based encryption)
Third-party authorization numbers (e.g., First Virtual)

3.3 E-Cash:
There are many ways that exist for implementing an e-cash system, all must incorporate a
few common features.
Electronic Cash is based on cryptographic systems called ―digital signatures‖.
This method involves a pair of numeric keys: one for locking (encoding) and the other for
unlocking (decoding).
E-cash must have the following four properties.
 
 Monetary value
 
 Interoperability
 
 Retrievability
 
Security

• Electronic cash is a general term that describes the attempts of several companies to

create value storage and exchange system that operates online in much the same way that

government-issued currency operates in the physical world.

• Concerns about electronic payment methods include:

– Privacy

– Security

– Independence

– Portability

Electronic Cash Storage:

• Two methods

– On-line

• Individual does not have possession personally of electronic cash

• Trusted third party, e.g. e-banking, bank holds customers‘ cash accounts

– Off-line

• Customer holds cash on smart card or electronic wallet

• Fraud and double spending require tamper-proof encryption

The purchase of e-cash from an on-line currency server (or bank) involves two steps:
 
 Establishment of an account
 
Maintaining enough money in the account to bank the purchase.

Once the tokens are purchased, the e-cash software on the customer‘s PC stores digital
money undersigned by a bank.
The users can spend the digital money at any shop accepting e-cash, without having to

DEPT OF CSE & IT

VSSUT, Burla
 open an account there or having to transmit credit card numbers.

As soon as the customer wants to make a payment, the software collects the necessary
amount from the stored tokens

– Convenience

3.4 Electronic Checks:

It is another form of electronic tokens.

Buyers must register with third-party account server before they are able to write
electronic checks.
The account server acts as a billing service.

DEPT OF CSE & IT

VSSUT, Burla
Advantages of Electronic Checks:
1. They work in the same way as traditional checks.
2. These are suited for clearing micropayments.
3. They create float & availability of float is an important for commerce.
4. Financial risk is assumed by the accounting server & may result in easier acceptance.

3.5 Smart Cards & Electronic Payment Systems:

Smart cards have been in existence since the early 1980s and hold promise for secure
transactions using existing infrastructure.

Smart cards are credit and debit cards and other card products enhanced with
microprocessors capable of holding more information than the traditional magnetic stripe.
The smart card technology is widely used in countries such as France, Germany, Japan,
and Singapore to pay for public phone calls, transportation, and shopper loyalty programs.
Types of Smart Cards:

Relationship-Based Smart Credit Cards

Electronic Purses also known as debit cards

 
 Relationship-Based Smart Credit Cards:

It is an enhancement of existing cards services &/ or the addition of new services that a

 financial institution delivers to its customers via a chip-based card or other device.

These services include access to multiple financial accounts, value-added marketing


programs, or other information card holders may want to store on their card.

 It includes access to multiple accounts, such as debit, credit, cash access, bill payment
& multiple access options at multiple locations.
 
 Electronic Purses:
To replace cash and place a financial instrument are racing to introduce electronic purses,
wallet-sized smart cards embedded with programmable microchips that store sums of

money for people to use instead of cash for everything.

DEPT OF CSE & IT

VSSUT, Burla
 The electronic purse works in the following manner:

After purse is loaded with money at an ATM, it can be used to pay for candy in a
vending machine with a card reader.

It verifies card is authentic & it has enough money, the value is deducted from balance
on the card & added to an e-cash & remaining balance is displayed by the vending
machine.
Credit Card-Based Electronic Payment Systems:
Payment cards are all types of plastic cards that consumers use to make purchases:
– Credit cards
• Such as a Visa or a MasterCard, has a preset spending limit based on the
user‘s credit limit.
– Debit cards
• Removes the amount of the charge from the cardholder‘s account and
transfers it to the seller‘s bank.
– Charge cards
• Such as one from American Express, carries no preset spending limit.
Advantages:
– Payment cards provide fraud protection.
– They have worldwide acceptance.
– They are good for online transactions.
Disadvantages:
Payment card service companies charge merchants per-transaction fees and monthly processing
fees.
3.6 Risks in Electronic Payment systems:
 
 Customer's risks

 – Stolen credentials or password

 – Dishonest merchant

 – Disputes over transaction
 
– Inappropriate use of transaction details
 
 Merchant‘s risk

– Forged or copied instruments

DEPT OF CSE & IT

VSSUT, Burla
 – Disputed charges
– Insufficient funds in customer‘s account
– Unauthorized redistribution of purchased items

3.7 Electronic payments Issues:

Secure transfer across internet
High reliability: no single failure point
Atomic transactions
Anonymity of buyer
Economic and computational efficiency: allow micropayments
Flexibility: across different methods
Scalability in number of servers and users

Security Requirements In Electronic Payment Systems:

 
 Integrity and authorization
A payment system with integrity allows no money to be taken from a user without explicit
authorization by that user. It may also disallow the receipt of payment without explicit
consent, to prevent occurrences of things like unsolicited bribery. Authorization constitutes
the most important relationship in a payment system. Payment can be authorized in three

ways: via out-band authorization, passwords, and signature.
 
 Out-band authorization
In this approach, the verifying party (typically a bank) notifies the authorizing party (the
payer) of a transaction. The authorizing party is required to approve or deny the payment
using a secure, out-band channel (such as via surface mail or the phone). This is the current
approach for credit cards involving mail orders and telephone orders: Anyone who knows a
user‘s credit card data can initiate transactions, and the legitimate user must check the
statement and actively complain about unauthorized transactions. If the user does not
complain within a certain time (usually 90 days), the transaction is considered ―approved‖

by default.
 
 Password authorization
A transaction protected by a password requires that every message from the authorizing party

include a cryptographic check value. The check value is computed using a secret

DEPT OF CSE & IT

VSSUT, Burla
 known only to the authorizing and verifying parties. This secret can be a personal
identification number, a password, or any form of shared secret. In addition, shared secrets
that are short - like a six-digit PIN - are inherently susceptible to various kinds of attacks.
They cannot by themselves provide a high degree of security. They should only be used to
control access to a physical token like a smart card (or a wallet) that performs the actual
authorization using secure cryptographic mechanisms, such as digital signatures.
 
 Signature authorization

In this type of transaction, the verifying party requires a digital signature of the authorizing
party. Digital signatures provide non repudiation of origin. 
 
 Confidentiality
Some parties involved may wish confidentiality of transactions. Confidentiality in this
context means the restriction of the knowledge about various pieces of information related
to a transaction: the identity of payer/payee, purchase content, amount, and so on. Typically,
the confidentiality requirement dictates that this information be restricted only to the
participants involved. Where anonymity or un-traceability are desired, the requirement may

be to limit this knowledge to certain subsets of the participants only, as described later.
 
 Availability and reliability
All parties require the ability to make or receive payments whenever necessary. Payment
transactions must be atomic: They occur entirely or not at all, but they never hang in an
unknown or inconsistent state. No payer would accept a loss of money (not a significant
amount, in any case) due to a network or system crash. Availability and reliability presume
that the underlying networking services and all software and hardware components are
sufficiently dependable. Recovery from crash failures requires some sort of stable storage at
all parties and specific resynchronization protocols. These fault tolerance issues are not

discussed here, because most payment systems do not address them explicitly.

3.8 Electronic Data Interchange(EDI):

Electronic Data Interchange (EDI) - interposes communication of business information in

standardized electronic form.

Prior to EDI, business depended on postal and phone systems that restricted
communication to those few hours of the workday that overlap between time zones.

DEPT OF CSE & IT

VSSUT, Burla
Why EDI?
• Reduction in transaction costs
• Foster closer relationships between trading partners
EDI & Electronic Commerce
• Electronic commerce includes EDI & much more
• EDI forges boundary less relationships by improving interchange of information between
trading partners, suppliers, & customers.
3.9 EDI layered architecture:
• Semantic (or application) layer
• Standards translation layer
• Packing (or transport) layer
• Physical network infrastructure layer

EDI semantic layer:

• Describes the business application
• Procurement example
– Requests for quotes
– Price quotes
– Purchase orders
– Acknowledgments
– Invoices
• Specific to company & software used

Standards translation:

DEPT OF CSE & IT

VSSUT, Burla
 • Specifies business form structure so that information can be exchanged
• Two competing standards
– American National Standards Institute(ANSI)X12
– EDIFACT developed by UN/ECE, Working Party for the Facilitation of
International Trade Procedures
EDI transport layer
• How the business form is sent, e.g. post, UPS, fax
• Increasingly, e-mail is the carrier
• Differentiating EDI from e-mail
– Emphasis on automation
– EDI has certain legal status

Physical network infrastructure layer

• Dial-up lines, Internet, value-added network, etc.
Information flow with EDI:

1. Buyer sends purchase order to seller computer

2. Seller sends purchase order confirmation to buyer
3. Seller sends booking request to transport company
4. Transport company sends booking confirmation to seller
5. Seller sends advance ship notice to buyer
6. Transport company sends status to seller
7. Buyer sends Receipt advice to seller

DEPT OF CSE & IT

VSSUT, Burla
 8. Seller sends invoice to buyer
9. Buyer sends payment to seller

3.10 Applications of EDI:

1. Role of EDI in international trade:
Reduced transaction expenditures
Quicker movement of imported & exported goods
Improved customer service through ―track & trace‖ programs
Faster customs clearance & reduced opportunities for corruption, a huge problem in trade

2. Interbank Electronic Funds Transfer (EFT)

• EFTS is credit transfers between banks where funds flow directly from the payer‘s bank
to the payee‘s bank.
• The two biggest funds transfer services in the United States are the Federal Reserve‘s
system, Fed wire, & the Clearing House Interbank Payments System (CHIPS) of the New
York clearing house
3. Health care EDI for insurance EDI
• Providing good & affordable health care is a universal problem
• EDI is becoming a permanent fixture in both insurance & health care industries as
medical provider, patients, & payers
• Electronic claim processing is quick & reduces the administrative costs of health care.
• Using EDI software, service providers prepare the forms & submit claims via
communication lines to the value-added network service provider
• The company then edits sorts & distributes forms to the payer. If necessary, the insurance
company can electronically route transactions to a third-party for price evaluation

• Claims submission also receives reports regarding claim status & request for additional
Information
4. Manufacturing & retail procurement using EDI
• These are heavy users of EDI
• In manufacturing, EDI is used to support just-in-time.
• In retailing, EDI is used to support quick response

DEPT OF CSE & IT

VSSUT, Burla
3.11 EDI Protocols:
  ANSI X12 
 
EDIFACT

Comparison of EDIFACT & X.12 Standards:

These are comprised of strings of data elements called segments.
A transaction set is a set of segments ordered as specified by the standard.

ANSI standards require each element to have a very specific name, such as order date or
invoice date.
EDIFACT segments, allow for multiuse elements, such as date.

EDIFACT has fewer data elements & segments & only one beginning segment
(header),but it has more composites.
It is an ever-evolving platform.

3.12 E-Marketing:
E-marketing is directly marketing a commercial message to a group of people using email.
In its broadest sense, every email sent to a potential or current customer could be considered
email marketing.

It usually involves using email to send ads, request business, or solicit sales or donations,
and is meant to build loyalty, trust, or brand awareness.

Email marketing can be done to either sold lists or a current customer database. Broadly,
the term is usually used to refer to sending email messages with the purpose of enhancing
the relationship of a merchant with its current or previous customers, to encourage
customer loyalty and repeat business, acquiring new customers or convincing current
customers to purchase something immediately, and adding advertisements to email
messages sent by other companies to their customers.

DEPT OF CSE & IT

VSSUT, Burla
Advantages:

An exact return on investment can be tracked and has proven to be high when done
properly. Email marketing is often reported as second only to search marketing as the most
effective online marketing tactic.

Email marketing is significantly cheaper and faster than traditional mail, mainly because
of high cost and time required in a traditional mail campaign for producing the artwork,
printing, addressing and mailing.

Advertisers can reach substantial numbers of email subscribers who have opted in (i.e.,
consented) to receive email communications on subjects of interest to them.

Almost half of American Internet users check or send email on a typical day with email
blasts that are delivered between 1 am and 5 am local time outperforming those sent at
other times in open and click rates.

Email is popular with digital marketers, rising an estimated 15% in 2009 to £292 m in the
UK.

If compared to standard email, direct email marketing produces higher response rate and
higher average order value for e-commerce businesses.

Disadvantages:

A report issued by the email services company Return Path, as of mid-2008 email
deliverability is still an issue for legitimate marketers. According to the report, legitimate
email servers averaged a delivery rate of 56%; twenty percent of the messages were
rejected, and eight percent were filtered.

Companies considering the use of an email marketing program must make sure that their
program does not violate spam laws such as the United States' Controlling the Assault of
Non-Solicited Pornography and Marketing Act (CAN-SPAM),the European Privacy and
Electronic Communications Regulations 2003, or their Internet service provider's
acceptable use policy.

DEPT OF CSE & IT

VSSUT, Burla
3.13 Tele Marketing:

Telemarketing is a method of direct marketing in which a salesperson solicits prospective

customers to buy products or services, either over the phone or through a subsequent face
to face or Web conferencing appointment scheduled during the call.

Telemarketing can also include recorded sales pitches programmed to be played over the
phone via automatic dialing.

Telemarketing may be done from a company office, from a call center, or from home. It
may involve a live operator voice broadcasting which is most frequently associated with
political messages.

An effective telemarketing process often involves two or more calls. The first call (or series
of calls) determines the customer‘s needs. The final call (or series of calls) motivates the
customer to make a purchase. Prospective customers are identified by various means,
including past purchase history, previous requests for information, credit limit, competition
entry forms, and application forms. Names may also be purchased from another company's
consumer database or obtained from a telephone directory or another public list. The
qualification process is intended to determine which customers are most likely to purchase
the product or service.

Charitable organizations, alumni associations, and political parties often use

telemarketing to solicit donations. Marketing research companies use telemarketing
techniques to survey the prospective or past customers of a client‘s business in order to
assess market acceptance of or satisfaction with a particular product, service, brand, or
company. Public opinion polls are conducted in a similar manner.

Telemarketing techniques are also applied to other forms of electronic marketing using e-
mail or fax messages, in which case they are frequently considered spam by receivers.

Disadvantages:

Telemarketing has been negatively associated with various scams and frauds, such as
pyramid schemes, and with deceptively overpriced products and services

Telemarketing is often criticized as an unethical business practice due to the perception of

high-pressure sales techniques during unsolicited calls.

DEPT OF CSE & IT

VSSUT, Burla
 Telemarketers marketing telephone companies may participate in telephone slamming, the
practice of switching a customer's telephone service without their knowledge or
authorization.

Telemarketing calls are often considered an annoyance, especially when they occur during
the dinner hour, early in the morning, or late in the evening.

3.14 Security Threats to E-commerce:

E-Commerce security requirements can be studied by examining the overall process, beginning
with the consumer and ending with the commerce server. Considering each logical link in the
commerce chain, the assets that must be protected to ensure secure e-commerce include client
computers, the messages travelling on the communication channel, and the web and commerce
servers – including any hardware attached to the servers. While telecommunications are certainly
one of the major assets to be protected, the telecommunications links are not the only concern in
computer and e-commerce security. For instance, if the telecommunications links were made
secure but no security measures were implemented for either client computers or commerce and
web-servers, then no communications security would exist at all.
Client threats
Until the introduction of executable web content, Web pages were mainly static. Coded in HTML,
static pages could do little more than display content and provide links to related pages with
additional information. However, the widespread use of active content has changed
this perception.
Active content: Active content refers to programs that are embedded transparently in web pages
and that cause action to occur. Active content can display moving graphics, download and play
audio, or implement web-based spreadsheet programs. Active content is used in e-commerce to
place items one wishes to purchase into a shopping cart and to compute the total invoice amount,
including sales tax, handling, and shipping costs. The best known active content forms are Java
applets, ActiveX controls, JavaScript, and VBScript.
Malicious codes: Computer viruses, worms and trojan horses are examples of malicious code. A
trojan horse is a program which performs a useful function, but performs an unexpected action as
well. Virus is a code segment which replicates by attaching copies to existing executables. A

DEPT OF CSE & IT

VSSUT, Burla
worm is a program which replicates itself and causes execution of the new copy. These can create
havoc on the client side.
Server-side masquerading: Masquerading lures a victim into believing that the entity with which
it is communicating is a different entity. For example, if a user tries to log into a computer across
the internet but instead reaches another computer that claims to be the desired one, the user has
been spoofed. This may be a passive attack (in which the user does not attempt to authenticate the
recipient, but merely accesses it), but it is usually an active attack.
Communication channel threats
The internet serves as the electronic chain linking a consumer (client) to an e-commerce resource.
Messages on the internet travel a random path from a source node to a destination node. The
message passes through a number of intermediate computers on the network before reaching the
final destination. It is impossible to guarantee that every computer on the internet through which
messages pass is safe, secure, and non-hostile.
Confidentiality threats: Confidentiality is the prevention of unauthorized information disclosure.
Breaching confidentiality on the internet is not difficult. Suppose one logs onto a website – say
www.anybiz.com – that contains a form with text boxes for name, address, and e-mail address.
When one fills out those text boxes and clicks the submit button, the information is sent to the
web-server for processing. One popular method of transmitting data to a web-server is to collect
the text box responses and place them at the end of the target server‘s URL. The captured data and
the HTTP request to send the data to the server is then sent. Now, suppose the user changes his
mind, decides not to wait for a response from the anybiz.com server, and jumps to another website
instead – say www.somecompany.com. The server somecompany.com may choose to collect web
demographics and log the URL from which the user just came (www.anybiz.com). By doing this,
somecompany.com has breached confidentiality by recording the secret information the user has
just entered.
Integrity threats: An integrity threat exists when an unauthorized party can alter a message stream
of information. Unprotected banking transactions are subject to integrity violations. Cyber
vandalism is an example of an integrity violation. Cyber vandalism is the electronic defacing of
an existing website page. Masquerading or spoofing – pretending to be someone you are not or
representing a website as an original when it really is a fake – is one means of creating havoc on
websites. Using a security hole in a domain name server (DNS), perpetrators can

DEPT OF CSE & IT

VSSUT, Burla
substitute the address of their website in place of the real one to spoof website visitors. Integrity
threats can alter vital financial, medical, or military information. It can have very serious
consequences for businesses and people.
Availability threats: The purpose of availability threats, also known as delay or denial threats, is
to disrupt normal computer processing or to deny processing entirely. For example, if the
processing speed of a single ATM machine transaction slows from one or two seconds to 30
seconds, users will abandon ATM machines entirely. Similarly, slowing any internet service will
drive customers to competitors‘ web or commerce sites.
Server threats
The server is the third link in the client-internet-server trio embodying the e-commerce path
between the user and a commerce server. Servers have vulnerabilities that can be exploited by
anyone determined to cause destruction or to illegally acquire information.
Web-server threats: Web-server software is designed to deliver web pages by responding to
HTTP requests. While web-server software is not inherently high-risk, it has been designed with
web service and convenience as the main design goal. The more complex the software is, the
higher the probability that it contains coding errors (bugs) and security holes – security weaknesses
that provide openings through which evildoers can enter.
Commerce server threats: The commerce server, along with the web-server, responds to requests
from web browsers through the HTTP protocol and CGI scripts. Several pieces of software
comprise the commerce server software suite, including an FTP server, a mail server, a remote
login server, and operating systems on host machines. Each of this software can have security
holes and bugs.
Database threats: E-commerce systems store user data and retrieve product information from
databases connected to the web-server. Besides product information, databases connected to the
web contain valuable and private information that could irreparably damage a company if it were
disclosed or altered. Some databases store username/password pairs in a non-secure way. If
someone obtains user authentication information, then he or she can masquerade as a legitimate
database user and reveal private and costly information.
Common gateway interface threats: A common gateway interface (CGI) implements the transfer
of information from a web-server to another program, such as a database program. CGI and the
programs to which they transfer data provide active content to web pages. Because CGIs

DEPT OF CSE & IT

VSSUT, Burla
are programs, they present a security threat if misused. Just like web-servers, CGI scripts can be
set up to run with their privileges set to high – unconstrained. Defective or malicious CGIs with
free access to system resources are capable of disabling the system, calling privileged (and
dangerous) base system programs that delete files, or viewing confidential customer information,
including usernames and passwords.
Password hacking: The simplest attack against a password-based system is to guess passwords.
Guessing of passwords requires that access to the complement, the complementation functions,
and the authentication functions be obtained. If none of these have changed by the time the
password is guessed, then the attacker can use the password to access the system.

3.15 Security Requirements For E-Commerce:

Authentication:

This is the ability to say that an electronic communication (whether via email or web) does
genuinely come from who it purports to.Without face-to-face contact, passing oneself off as
someone else is not difficult on the internet.
In online commerce the best defence against being misled by an imposter is provided by
unforgeable digital certificates from a trusted authority (such as VeriSign). Although anyone can
generate digital certificates for themselves, a trusted authority demands real-world proof of identity
and checks its validity before issuing a digital certificate. Only certificates from trusted authorities
will be automatically recognized and trusted by the major web browser and email client software.
Authentication can be provided in some situations by physical tokens (such as a drivers license),
by a piece of information known only to the person involved (eg. a PIN), or by a physical property
of a person (fingerprints or retina scans). Strong authentication requires at least two or more of
these. A digital certificate provides strong authentication as it is a unique token and requires a
password for its usage.
Privacy:
In online commerce, privacy is the ability to ensure that information is accessed and changed only
by authorized parties. Typically this is achieved via encryption. Sensitive data (such as credit card
details, health records, sales figures etc.) are encrypted before being transmitted across the open
internet – via email or the web. Data which has been protected with strong 128-bit encryption may
be intercepted by hackers, but cannot be decrypted by them within a short

DEPT OF CSE & IT

VSSUT, Burla
time. Again, digital certificates are used here to encrypt email or establish a secure HTTPS
connection with a web-server. For extra security, data can also be stored long-term in an encrypted
format.

Authorization:
Authorization allows a person or computer system to determine if someone has the authority to
request or approve an action or information. In the physical world, authentication is usually
achieved by forms requiring signatures, or locks where only authorized individuals hold the keys.
Authorization is tied with authentication. If a system can securely verify that a request for
information (such as a web page) or a service (such as a purchase requisition) has come from a
known individual, the system can then check against its internal rules to see if that person has
sufficient authority for the request to proceed.
In the online world, authorization can be achieved by a manager sending a digitally signed email.
Such an email, once checked and verified by the recipient, is a legally binding request for a service.
Similarly, if a web-server has a restricted access area, the server can request a digital certificate
from the user‘s browser to identify the user and then determine if they should be given access to
the information according to the server‘s permission rules.

Integrity:
Integrity of information means ensuring that a communication received has not been altered or
tampered with. Traditionally, this problem has been dealt with by having tight control over access
to paper documents and requiring authorized officers to initial all changes made – a system with
obvious drawbacks and limitations. If someone is receiving sensitive information online, he not
only wants to ensure that it is coming from who he expects it to (authentication), but also that it
hasn‘t been intercepted by a hacker while in transit and its contents altered. The speed and
distances involved in online communications requires a very different approach to this problem
from traditional methods.

One solution is afforded by using digital certificates to digitally ―sign‖ messages. A travelling
employee can send production orders with integrity to the central office by using their digital
certificate to sign their email. The signature includes a hash of the original message – a brief

DEPT OF CSE & IT

VSSUT, Burla
numerical representation of the message content. When the recipient opens the message, his email
software will automatically create a new hash of the message and compare it against the one
included in the digital signature. If even a single character has been altered in the message, the two
hashes will differ and the software will alert the recipient that the email has been tampered with
during transit.
Non-repudiation:
Non-repudiation is the ability to guarantee that once someone has requested a service or approved
an action. Non-repudiation allows one to legally prove that a person has sent a specific email or
made a purchase approval from a website. Traditionally non-repudiation has been achieved by
having parties sign contracts and then have the contracts notarized by trusted third parties. Sending
documents involved the use of registered mail, and postmarks and signatures to date-stamp and
record the process of transmission and acceptance. In the realm of e-commerce, non repudiation is
achieved by using digital signatures. Digital signatures which have been issued by a trusted
authority (such as VeriSign) cannot be forged and their validity can be checked with any major
email or web browser software. A digital signature is only installed in the personal computer of its
owner, who is usually required to provide a password to make use of the digital signature to encrypt
or digitally sign their communications. If a company receives a purchase order via email which
has been digitally signed, it has the same legal assurances as on receipt of a physical signed
contract.

3.16 Security policy for E-commerce:

The security policy may cover issues like:
What service types (e.g., web, FTP, SMTP) users may have access to?

What classes of information exist within the organization and which should be encrypted
before being transmitted?

What client data does the organization hold. How sensitive is it? How is it to be protected?
What class of employees may have remote access to the corporate network?

Roles and responsibilities of managers and employees in implementing the security policy.
How security breaches are to be responded to?

DEPT OF CSE & IT

VSSUT, Burla
The security policy should also consider physical aspects of network security. For example,
Who has access to the corporate server?
Is it in a locked environment or kept in an open office?

What is the procedure for determining who should be given access? The security policy
regulates the activities of employees just as much as it defines how IT infrastructure will
be configured. The policy should include details on how it is to be enforced
How individual responsibilities are determined?
For it to be effective, the policy needs regular testing and review to judge the security measures.
The review process needs to take into account any changes in technology or business practices
which may have an influence upon security. Lastly, the policy itself needs to be regarded as a
living document which will be updated at set intervals to reflect the evolving ways in which the
business, customers and technology interact.
Security Standards:
There are various standards pertaining to the security aspects of enterprises. Some of them are

 
ISO 17799 (Information technology – Code of practice for information security
management).
 
 (ISO/IEC 2000).
 
 SSE-CMM (Systems security engineering – Capability maturity model).
 
 (SSE-CMM 2003).
 
 COBIT (Control objectives for information and related technology).
 
(COBIT 2000).

ISO 17799 provides detailed guidelines on how a management framework for enterprise security
should be implemented. It conceives ten security domains. Under each domain there are certain
security objectives to be fulfilled. Each objective can be attained by a number of controls. The
controls may prescribe management measures like guidelines and procedures, or some security
infrastructure in the form of tools and techniques. It details various methods that can be followed
by enterprises to meet security needs for e-commerce. It talks about the need for security policies,
security infrastructure, and continuous testing in
the same manner as has been detailed above.

DEPT OF CSE & IT

VSSUT, Burla
The main objective of the COBIT is the development of clear policies and good practices for
security and control in IT for worldwide endorsement by commercial, governmental and
professional organizations. The SSE-CMM is a process reference model. It is focused upon the
requirements for implementing security in a system or series of related systems that are in the
Information Technology Security domain.

3.17 Firewall:

A firewall is a network security system that controls the incoming and outgoing network traffic
based on an applied rule set. A firewall establishes a barrier between a trusted, secure internal
network and another network (e.g., the Internet) that is assumed not to be secure and trusted.
Firewalls exist both as software to run on general purpose hardware and as a hardware appliance.
Many hardware-based firewalls also offer other functionality to the internal network they protect,
such as acting as a DHCP server for that network.

Many personal computer operating systems include software-based firewalls to protect against
threats from the public Internet. Many routers that pass data between networks contain firewall
components and, conversely, many firewalls can perform basic routing functions.

Types of Firewall:

There are different types of firewalls depending on where the communication is taking place,
where the communication is intercepted and the state that is being traced.

Network layer Firewall

Application layer firewall
Proxy server
Network address translation


Network layer Firewall:
Network layer firewalls, also called packet filters, operate at a relatively low level of the
TCP/IP protocol stack, not allowing packets to pass through the firewall unless they match
the established rule set. The firewall administrator may define the rules; or default rules may
apply.

DEPT OF CSE & IT

VSSUT, Burla
 Network layer firewalls generally fall into two sub-categories,
Stateful Firewalls
Stateless Firewalls

Stateful firewalls maintain context about active sessions, and use that "state information" to
speed packet processing. Any existing network connection can be described by several
properties, including source and destination IP address, UDP or TCP ports, and the current
stage of the connection's lifetime (including session initiation, handshaking, data transfer,
or completion connection). If a packet does not match an existing connection, it will be
evaluated according to the rule set for new connections. If a packet matches an existing
connection based on comparison with the firewall's state table, it will be allowed to pass
without further processing.
Stateless firewalls require less memory, and can be faster for simple filters that require less
time to filter than to look up a session. They may also be necessary for filtering stateless
network protocols that have no concept of a session. However, they cannot make more
complex decisions based on what stage communications between hosts have reached.

 
 Application Layer Firewall:

Application-layer firewalls work on the application level of the TCP/IP stack (i.e., all
browser traffic, or all telnet or ftp traffic), and may intercept all packets traveling to or
from an application. They block other packets (usually dropping them without

acknowledgment to the sender).

On inspecting all packets for improper content, firewalls can restrict or prevent outright the
spread of networked computer worms and trojans. The additional inspection criteria can

add extra latency to the forwarding of packets to their destination.

Application firewalls function by determining whether a process should accept any given
connection. Application firewalls accomplish their function by hooking into socket calls to
filter the connections between the application layer and the lower layers of the OSI model.

Application firewalls that hook into socket calls are also referred to as socket

DEPT OF CSE & IT

VSSUT, Burla
 filters. Application firewalls work much like a packet filter but application filters apply
filtering rules (allow/block) on a per process basis instead of filtering connections on a per
port basis. Generally, prompts are used to define rules for processes that have not yet
received a connection. It is rare to find application firewalls not combined or used in
conjunction with a packet filter.

Also, application firewalls further filter connections by examining the process ID of data
packets against a ruleset for the local process involved in the data transmission. The extent
of the filtering that occurs is defined by the provided ruleset. Given the variety of software
that exists, application firewalls only have more complex rulesets for the standard services,
such as sharing services. These per process rulesets have limited efficacy in filtering every
possible association that may occur with other processes.

 
 Proxy server:

A proxy server running either on dedicated hardware or as software on a general-purpose
machine may act as a firewall by responding to input packets (connection requests, for
example) in the manner of an application, while blocking other packets. A proxy server is
a gateway from one network to another for a specific network application, in the sense that

it functions as a proxy on behalf of the network user.

Proxies make tampering with an internal system from the external network more difficult
and misuse of one internal system would not necessarily cause a security breach exploitable
from outside the firewall. Conversely, intruders may hijack a publicly reachable system
and use it as a proxy for their own purposes; the proxy then masquerades as that system to
other internal machines. While use of internal address spaces enhances security, crackers
may still employ methods such as IP spoofing to attempt to pass packets to a target

network.

DEPT OF CSE & IT

VSSUT, Burla
  
 Network Address Translation:

Firewalls often have network address translation (NAT) functionality, and the hosts
protected behind a firewall commonly have addresses in the "private address range", as

defined in RFC 1918.

Firewalls often have such functionality to hide the true address of protected hosts.
Originally, the NAT function was developed to address the limited number of IPv4 routable
addresses that could be used or assigned to companies or individuals as well as reduce both
the amount and therefore cost of obtaining enough public addresses for every computer in
an organization. Hiding the addresses of protected devices has become an increasingly

important defense against network reconnaissance.

3.18 Digital Signatures:

A digital signature is a mathematical scheme for demonstrating the authenticity of a digital
message or document. A valid digital signature gives a recipient reason to believe that the message
was created by a known sender, such that the sender cannot deny having sent the message
(authentication and non-repudiation) and that the message was not altered in transit (integrity).
Digital signatures are commonly used for software distribution, financial transactions, and in other
cases where it is important to detect forgery or tampering.
Digital signatures are often used to implement electronic signatures, a broader term that refers to
any electronic data that carries the intent of a signature, but not all electronic signatures use digital
signatures. In some countries, including the United States, India, Brazil, and members of the
European Union, electronic signatures have legal significance.

A digital signature scheme typically consists of three algorithms;

A key generation algorithm that selects a private key uniformly at random from a set of
possible private keys. The algorithm outputs the private key and a corresponding public
key.
A signing algorithm that, given a message and a private key, produces a signature.

DEPT OF CSE & IT

VSSUT, Burla
 A signature verifying algorithm that, given a message, public key and a signature, either
accepts or rejects the message's claim to authenticity.
Applications of digital signatures:

Authentication:

Although messages may often include information about the entity sending a message, that
information may not be accurate. Digital signatures can be used to authenticate the source of
messages. When ownership of a digital signature secret key is bound to a specific user, a valid
signature shows that the message was sent by that user. The importance of high confidence in
sender authenticity is especially obvious in a financial context. For example, suppose a bank's
branch office sends instructions to the central office requesting a change in the balance of an
account. If the central office is not convinced that such a message is truly sent from an authorized
source, acting on such a request could be a grave mistake.

Integrity:

In many scenarios, the sender and receiver of a message may have a need for confidence that the
message has not been altered during transmission. Although encryption hides the contents of a
message, it may be possible to change an encrypted message without understanding it. (Some
encryption algorithms, known as nonmalleable ones, prevent this, but others do not.) However, if
a message is digitally signed, any change in the message after signature invalidates the signature.
Furthermore, there is no efficient way to modify a message and its signature to produce a new
message with a valid signature, because this is still considered to be computationally infeasible by
most cryptographic hash functions (see collision resistance).

Non-repudiation:

Non-repudiation, or more specifically non-repudiation of origin, is an important aspect of digital

signatures. By this property, an entity that has signed some information cannot at a later time deny
having signed it. Similarly, access to the public key only does not enable a fraudulent party to fake
a valid signature.

DEPT OF CSE & IT

VSSUT, Burla
Some digital signature algorithms:

RSA-based signature schemes, such as RSA-

PSS DSA and its elliptic curve variant ECDSA
ElGamal signature scheme as the predecessor to DSA, and variants Schnorr signature and
Pointcheval–Stern signature algorithm
Rabin signature algorithm Pairing-
based schemes such as BLS
Undeniable signatures
Aggregate signature - a signature scheme that supports aggregation: Given n signatures on
n messages from n users, it is possible to aggregate all these signatures into a single
signature whose size is constant in the number of users. This single signature will convince
the verifier that the n users did indeed sign the n original messages.
Signatures with efficient protocols - are signature schemes that facilitate efficient
cryptographic protocols such as zero-knowledge proofs or secure computation.

3.19 Digital Certificate:

It is an electronic document used to prove ownership of a public key. The certificate

includes information about the key, information about its owner's identity, and the digital
signature of an entity that has verified the certificate's contents are correct. If the signature
is valid, and the person examining the certificate trusts the signer, then they know they can
use that key to communicate with its owner.

The most common use of a digital certificate is to verify that a user sending a message is
who he or she claims to be, and to provide the receiver with the means to encode a reply.
An individual wishing to send an encrypted message applies for a digital certificate from a
Certificate Authority (CA). The CA issues an encrypted digital certificate containing the
applicant's public key and a variety of other identification information. The CA makes its
own public key readily available through print publicity or perhaps on the Internet.

The recipient of an encrypted message uses the CA's public key to decode the digital
certificate attached to the message, verifies it as issued by the CA and then obtains the

DEPT OF CSE & IT

VSSUT, Burla
 sender's public key and identification information held within the certificate. With this
information, the recipient can send an encrypted reply.
The most widely used standard for digital certificates is X.509.

Contents Of a Typical Digital Certificate:

Serial Number: Used to uniquely identify the certificate.

Subject: The person, or entity identified.
Signature Algorithm: The algorithm used to create the signature.
Signature: The actual signature to verify that it came from the issuer.
Issuer: The entity that verified the information and issued the certificate.
Valid-From: The date the certificate is first valid from.
Valid-To: The expiration date.
Key-Usage: Purpose of the public key (e.g. encipherment, signature, certificate
signing...).
Public Key: The public key.
Thumbprint Algorithm: The algorithm used to hash the public key certificate.
Thumbprint (also known as fingerprint): The hash itself, used as an abbreviated form of
the public key certificate.

4.1 Enterprise Resource Planning:

Enterprise resource planning (ERP) is business management software—usually a suite of
integrated applications—that a company can use to collect, store, manage and interpret data from
many business activities, including:
Product planning, cost
Manufacturing or service delivery
Marketing and sales
Inventory management
Shipping and payment



ERP provides an integrated view of core business processes, often in real-time, using
 common databases maintained by a database management system. ERP systems track
business resources—cash, raw materials, production capacity—and the status of business
commitments: orders, purchase orders, and payroll. The applications that make up the
system share data across the various departments that provide the data. ERP facilitates
information flow between all business functions, and manages connections to outside

 stakeholders.


Enterprise system software is a multi-billion dollar industry that produces components
 that support a variety of business functions. IT investments have become the largest
category of capital expenditure in United States-based businesses over the past decade.
Though early ERP systems focused on large enterprises, smaller enterprises increasingly

 use ERP systems.

The ERP system is considered a vital organizational tool because it integrates varied
 organizational systems and facilitates error-free transactions and production. However,

 ERP system development is different from traditional systems development.

ERP systems run on a variety of computer hardware  and network configurations,
typically using a database as an information repository.

4.2 Functional areas of ERP:

An ERP system covers the following common functional areas. In many ERP systems these are
called and grouped together as ERP modules:

Financial accounting: General ledger, fixed asset, payables including vouchering,

matching and payment, receivables cash application and collections, cash management,
financial consolidation
Management accounting: Budgeting, costing, cost management, activity based costing
Human resources: Recruiting, training, rostering, payroll, benefits, 401K, diversity
management, retirement, separation
Manufacturing: Engineering, bill of materials, work orders, scheduling, capacity,
workflow management, quality control, manufacturing process, manufacturing projects,
manufacturing flow, product life cycle management
Order Processing: Order to cash, order entry, credit checking, pricing, available to
promise, inventory, shipping, sales analysis and reporting, sales commissioning.
Supply chain management: Supply chain planning, supplier scheduling, product
configurator, order to cash, purchasing, inventory, claim processing, warehousing
(receiving, putaway, picking and packing).
Project management: Project planning, resource planning, project costing, work
breakdown structure, billing, time and expense, performance units, activity management
Customer relationship management: Sales and marketing, commissions, service, customer
contact, call center support - CRM systems are not always considered part of ERP systems
but rather Business Support systems (BSS).
Data services : Various "self–service" interfaces for customers, suppliers and/or
employees.

4.3 Benefits of ERP:
ERP can improve quality and efficiency of the business. By keeping a company's internal
business processes running smoothly, ERP can lead to better outputs that may benefit the
company, such as in customer service and manufacturing.
ERP supports upper level management by providing information for decision making. ERP
creates a more agile company that adapts better to change. ERP makes a company more
flexible and less rigidly structured so organization components operate more cohesively,
enhancing the business—internally and externally.

ERP can improve data security. A common control system, such as the kind offered by
ERP systems, allows organizations the ability to more easily ensure key company data is
not compromised.
ERP provides increased opportunities for collaboration. Data takes many forms in the
modern enterprise. Documents, files, forms, audio and video, emails. Often, each data
medium has its own mechanism for allowing collaboration. ERP provides a collaborative
platform that lets employees spend more time collaborating on content rather than
mastering the learning curve of communicating in various formats across distributed
systems.
4.4 Disadvantages of ERP:
Customization can be problematic. Compared to the best-of-breed approach, ERP can be
seen as meeting an organization‘s lowest common denominator needs, forcing the
organization to find workarounds to meet unique demands.

DEPT OF CSE & IT

VSSUT, Burla
 Re-engineering business processes to fit the ERP system may damage competitiveness or
divert focus from other critical activities.
ERP can cost more than less integrated or less comprehensive solutions.
High ERP switching costs can increase the ERP vendor's negotiating power, which can
increase support, maintenance, and upgrade expenses.
Overcoming resistance to sharing sensitive information between departments can divert
management attention.
Integration of truly independent businesses can create unnecessary dependencies.
Extensive training requirements take resources from daily operations.

Due to ERP's architecture (OLTP, On-Line Transaction Processing) ERP systems are not
well suited for production planning and supply chain management (SCM). Harmonization
of ERP systems can be a mammoth task (especially for big companies) and requires a lot
of time, planning, and money.

4.5 Business Process Redesign:


  on the analysis and design of workflows and
It is a business management strategy focusing
business processes within an organization.

BPR aimed to help organizations fundamentally rethink how they do their work in order
 improve customer service, cut operational costs, and become world-class
to dramatically
competitors.

Business Process Reengineering (BPR) is the practice of rethinking and redesigning the
way work is done to better support an organization's mission and reduce costs.
Reengineering starts with a 
high-level assessment of the organization's mission, strategic
 goals, and customer needs.

Within the framework of this basic assessment of mission and goals, re-engineering
focuses on the organization's business processes—the steps and procedures that govern
how resources are used to create products and services that meet the needs of particular
customers or markets. As a structured ordering of work steps across time and place, a
business process can be decomposed into specific activities, measured, modeled, and
improved. It can also be completely redesigned or eliminated altogether. Re-engineering
identifies, analyzes, and re-designs an organization's core business processes with the aim
of achieving dramatic improvements
 in critical performance measures, such as cost,
 quality, service, and speed.

Re-engineering recognizes that an organization's business processes are usually fragmented into
subprocesses and tasks that are carried out by several specialized

DEPT OF CSE & IT

VSSUT, Burla
functional areas within the organization. Often, no one is responsible for the overall
performance of the entire process. Re-engineering maintains that optimizing the
performance of sub processes can result in some benefits, but cannot yield dramatic
improvements if the process itself is fundamentally inefficient and outmoded. For that
reason, re-engineering focuses on re-designing the process as a whole in order to achieve
the greatest possible benefits to the organization and their customers. This drive for
realizing dramatic improvements by fundamentally re-thinking how the organization's
work should be done distinguishes re-engineering from process improvement efforts that
focus on functional or incremental improvement.

 4.6 Knowledge Engineering:
Knowledge Engineering (KE) refers to all technical, scientific and social aspects involved in
building, maintaining and using knowledge-based systems.

There were essentially two approaches that were attempted:

1. Use conventional software development methodologies

2. Develop special methodologies tuned to the requirements of building expert systems

Many of the early expert systems were developed by large consulting and system integration firms
such as Andersen Consulting. These firms already had well tested conventional waterfall
methodologies (e.g. Method/1 for Andersen) that they trained all their staff in and that were
virtually always used to develop software for their clients. One trend in early expert systems
development was to simply apply these waterfall methods to expert systems development.

Another issue with using conventional methods to develop expert systems was that due to the
unprecedented nature of expert systems they were one of the first applications to adopt rapid
application development methods that feature iteration and prototyping as well as or instead of
detailed analysis and design. In the 1980s few conventional software methods supported this type
of approach.

The final issue with using conventional methods to develop expert systems was the need for
knowledge acquisition. Knowledge acquisition refers to the process of gathering expert
knowledge and capturing it in the form of rules and ontologies. Knowledge acquisition has special
requirements beyond the conventional specification process used to capture most business
requirements.

These issues led to the second approach to knowledge engineering: development of custom
methodologies specifically designed to build expert systems. [1] One of the first and most popular
of such methodologies custom designed for expert systems was the Knowledge Acquisition and
Documentation Structuring (KADS) methodology developed in Europe.

4.7 Business Modules In ERP:
The important modules in ERP are
 
 Finance:

The entire concept of information technology is based on the premise that providing the 
 right information, to the right people, at the right timecan make a critical difference to the

 organization.

Much of this key information could be taken from the financial data. But merely having
 the financial data is not enough.

You need a set of processes and views of your data that provided up-to-the minutefinancial
 information in exactly the form you need it to make that critical difference and

 help with that critical decision.


Accounting software needs access to information in each area of organisation, from R&D
 and market research through manufacturing, distribution and sales.

Financial solution must provide the management with information that  can be leveraged
 for strategic decisions, in order to achieve comprehensive advantage.

on
In today‘s business enterprise, you need to know that your financial decisions are based
 today‘s data, not numbers from records closed a month ago, or even a week ago.And
you need to know that this same ‗today‘s‘ data represents every segment of your
organization's activities, whether your enterprise stretches across a room or around the

 globe.

This is essential, because the most efficient way
to get our enterprise to where you want it
 tomorrow is to know exactly where it is today.


What ever be the financial goals of the organization, the financial application components
 of the ERP solutions work hand-in-hand to improve the bottom line.
 
The Finance modules of the most ERP systems provide financial functionality and analysis
 

 phase) to production planning and product development (planning phase) to procurement

 and sales and distribution, as well as into the entire usage phase.


Computer-integrated Quality Management (CIQ) is more appropriate term in comparison
 to Computer-Aided Quality Management (CAQ), because an isolated CAQ system

cannot carry out the comprehensive tasks of a quality management system.

4.9 Enterprise application integration(EAI):


Enterprise application integration (EAI) is the use of software and computer systems'
 architectural principles to integrate a set of enterprise computer applications.

Enterprise application integration is the process of linking such applications within
a single
 organization together in order to simplify and automate business processes to the
greatest extent possible, while at the same time avoiding having to make sweeping changes
to the existing applications or data structures. Applications can be linked either at the back-

 end (database) or the front-end (GUI).

The various systems that need to be linked together may reside on different operating 
 systems, use different database solutions or computer languages, or different date and
time formats, or may be legacy systems that are no longer supported by the vendor who
originally created them. In some cases, such systems are dubbed "stovepipe systems"
because they consist of components that have been jammed together in a way that makes

it very hard to modify them in any way.

EAI can be used for different purposes:

Data integration: Ensures that information in multiple systems is kept consistent. This is
also known as enterprise information integration (EII).

DEPT OF CSE & IT

VSSUT, Burla
 Vendor independence: Extracts business policies or rules from applications and
implements them in the EAI system, so that even if one of the business applications is
replaced with a different vendor's application, the business rules do not have to be re-
implemented.

Common facade: An EAI system can front-end a cluster of applications, providing a single
consistent access interface to these applications and shielding users from having to learn to
use different software packages.

Multiple technologies are used in implementing each of the components of the EAI system:

Bus/hub:

This is usually implemented by enhancing standard middleware products (application server,

message bus) or implemented as a stand-alone program (i. e., does not use any middleware), acting
as its own middleware.

Application connectivity:

The bus/hub connects to applications through a set of adapters (also referred to as connectors).
These are programs that know how to interact with an underlying business application. The adapter
performs two-way communication, performing requests from the hub against the application, and
notifying the hub when an event of interest occurs in the application (a new record inserted, a
transaction completed, etc.). Adapters can be specific to an application (e. g., built against the
application vendor's client libraries) or specific to a class of applications (e. g., can interact with
any application through a standard communication protocol, such as SOAP, SMTP or Action
Message Format (AMF)). The adapter could reside in the same process space as the bus/hub or
execute in a remote location and interact with the hub/bus through industry standard protocols such
as message queues, web services, or even use a proprietary protocol. In the Java world, standards
such as JCA allow adapters to be created in a vendor-neutral manner.

Data format and transformation:

To avoid every adapter having to convert data to/from every other applications' formats, EAI
systems usually stipulate an application-independent (or common) data format. The EAI system
usually provides a data transformation service as well to help convert between application-

DEPT OF CSE & IT

VSSUT, Burla
specific and common formats. This is done in two steps: the adapter converts information from the
application's format to the bus's common format. Then, semantic transformations are applied on
this (converting zip codes to city names, splitting/merging objects from one application into
objects in the other applications, and so on).

Integration modules:

An EAI system could be participating in multiple concurrent integration operations at any given
time, each type of integration being processed by a different integration module. Integration
modules subscribe to events of specific types and process notifications that they receive when
these events occur. These modules could be implemented in different ways: on Java-based EAI
systems, these could be web applications or EJBs or even POJOs that conform to the EAI system's
specifications.

Support for transactions:

When used for process integration, the EAI system also provides transactional consistency across
applications by executing all integration operations across all applications in a single overarching
distributed transaction (using two-phase commit protocols or compensating transactions).

Disadvantages of EAI:

1. Constant change: The very nature of EAI is dynamic and requires dynamic project
managers to manage their implementation.
2. Shortage of EAI experts: EAI requires knowledge of many issues and technical aspects.
3. Competing standards: Within the EAI field, the paradox is that EAI standards themselves
are not universal.
4. EAI is a tool paradigm: EAI is not a tool, but rather a system and should be implemented
as such.
5. Building interfaces is an art: Engineering the solution is not sufficient. Solutions need to
be negotiated with user departments to reach a common consensus on the final outcome.
A lack of consensus on interface designs leads to excessive effort to map between various
systems data requirements.
6. Loss of detail: Information that seemed unimportant at an earlier stage may become crucial
later.
7. Accountability: Since so many departments have many conflicting requirements, there
should be clear accountability for the system's final structure.
